The present invention provides a process for producing an aromatic unsaturated compound of the formula (4)
wherein Ar represents an optionally substituted aromatic group or an optionally substituted heteroaromatic group, and Y represents an electron withdrawing group,
which comprises reacting
(a) a compound of the formula (1)
Ar—H (1)
wherein Ar has the same meaning as defined above with
(b) a compound of the formula (2)
wherein Y has the same meaning as defined above, and Z represents a lower alkoxy, or
a compound of the formula (3)
wherein Y and Z have the same meanings as defined above, in the presence of
(c) an acid or a compound which generates a mineral acid by its hydrolysis.
